Definitions
- the invention relates to a vacuum pump with a gas-tight electrical housing passage.
- the vacuum pump according to the invention has a vacuum-tight housing and an electrical component within the housing.
- the gas-tight electrical feedthrough for establishing an electrical connection between the electrical component and the housing outer side is formed by a housing opening, a potting compound body seated on the housing opening with an electrical line between the housing inner side and the housing outer side a sealing ring between the opening edge of the housing opening and the potting compound body and a fixation for fixing the potting compound body to the housing.
- the electrical line may, according to a preferred embodiment, have a circuit board located in the potting compound.
- the electrical line is thus partially realized in the form of a conductor on a printed circuit board.
- the electrical line may further each have an inner housing to the housing and a housing outside of the potting compound body protruding electrical connector.
- the two electrical connectors may be interconnected by the printed circuit board, but may be electrically connected to each other in other ways.
- the circuit board has electronic components.
- electronic components all electronic components are conceivable that can serve a gain, interference suppression or other manipulation of electrical signals, such as amplifiers, suppression chokes and capacitors, integrated circuits for signal processing, etc.
- the electronic component is preferably a readable pump data memory in which pump-specific functional parameters, for example a fault history of the relevant vacuum pump, are stored and can be called up at any time.
- a vacuum pump 10 is shown schematically, which may be designed as a positive displacement pump, but in particular as a high vacuum turbomolecular pump is formed with a magnetic bearing.
- the vacuum pump 10 has a gas-tight electrical feedthrough 20 for producing an electrical connection between the electrical components 14, 16, 18 and the outside of the housing.
- the feedthrough 20 is essentially formed by a housing opening 22 in the housing wall 13, a potting compound body 24 seated on the housing opening 22 from the outside, an elastic sealing ring 26 between an opening edge 28 of the housing opening 22, and a potting compound Housing 30 formed fixation 32 and an electrical line 34 is formed.
- the sealing ring 26 is seated in a ring groove 27 in the potting compound body 24th
- the potting material is an epoxy resin.
- the epoxy resin can be admixed with fine-grained admixtures which positively change the thermal expansion, the thermal conductivity and / or other physical parameters.
- the fixing 32 By the fixing 32 forming cup-shaped Vergussmassen housing 30 which is fixed on the outside of the housing 30, for example, screwed, the potting compound body 24 is pressed onto the opening edge 28 and thereby a gas-tight and vacuum-tight seal between the opening edge 28 and the potting compound -Body 24 produced.
